The principle of multi-touch screen
- Aug 13, 2018 -


Multi-touch screen principle, for the convenience of operation, people use touch screen instead of mouse or keyboard.To do this, touch the touchscreen on the front of the display with a finger or other object, and the system then positions the selection input based on the finger's icon or menu position.The touch screen consists of touch detection component and touch screen controller.The touch detection part is installed in front of the display screen to detect the user's touch position, which is accepted and sent to the touch screen controller;The main function of the touch screen controller is to receive touch information from the touch point detection device, convert it into contact coordinates, and send it to CPU, which can accept and execute commands from CPU at the same time.
